TIRE.

Specification of Letters Patent.

Patented April 20, 1909.

Applicatic'n filed February 5,1907. Serial No. 856,911.

United States, residing at Akron, in the county of Summit 'and'State'of Ohio, have invented a new and useful Tire, of which the following is a specification.

This invention has relation to tires, and it .conslsts 1n the novel construction and ar-' 10' rangement of its and described.

The object of the invention is to provide an elastic tire which is so constructed as to stand up and maintain its proper configuraparts ashereinafter shown tion and resiliency without being inflated and in which thoseparts that contact with the wheel rim will be protected fromwear. As the tire isnot subjected to greater pressure than atmosphericpressure there is no danger of the tire'collapsing a'sa consequence of being punctured.

The 47116 consists primarily of an outer flexible sheath made 'of rubber or a mixture of rubber and fiber and lined with a flexible material such as canvas; which is continued around the rim-engaging portions of the sheath to provide shields to protect. such portions from wear. A continuous hollowtube fits within the sheath and the edges of the sheath are held in contact with the wheel rim by suitable wedge shaped-members lo-j cated'at intervals upon the rim of the Wheel and provided with means for forcingand holding the edges of the sheath inicontac't with the flanges of the wheel rim. The

sheath is provided with annular flanges which fit over the flanges of the ,wheel rim:

and prevent ingress of moisturebetween the sheath and the wheel run.

In the accompanying. drawing :,-Figure is a side elevation ofa portion of the: tire.

tube

The wheel rim; 1 is provided at'ltsedges with the inwardly curved flanges 2, 2. The

sheath 3 is made of rubber 'or'a mixture of J. Gosr--' LIN and LOUIS MUELLER, Jr., citizens of the crease the resiliency of the tube 6.

Fig. 4 is a transverse-sectional viewof a modified form oithe inner continuous.

the rim l. The sheath 3 is lined with a material 5 such as canvas which is carried around the rim -engaging portions of the sheath and constitutes a shield to protect the sheath-from wear. The continuous imperforated tube 6 fits within the sheath 3, and is of sufficient thickness to give the tire proper resiliency, and as the tube is not in? flatedwith air at a greater prcssure'than almospheric pressure it will not collapse should it be punctured, but will always stand up and hold the sheath 3 in proper position.

' As shown in Fig. 4 of the drawing the tube. 6 may be reinforced by an additional tube 7 located therein, the object of which is to rilw 1c wedges 8 are located at intervals along the rim, of the wheel and each wedge is provided with a screw threaded shank 9 which passes transversely through the wheel rim and mto the felly 12. The folly 12 is provided with radial openings 13 each reduced at its upper termina to form a shoulder within .the opening 13. The sleeves 10 are journaledfor rotationin the openings 13 mthe felliv and are" internally threaded to receive the shanks 9,

the upper terminals of the sleeves being ar-- ranged to abut against the shoulder of the opening 13. Each of the sleeveslO has a head 11 arranged to contact with the surface of the fell 12. simultaneouslywith the-engagement etween the terminalfof.theisleeve and theshoulder in the opening 13, whereby the said sleeves .10 are given .a firmbearing andlthe strain well distributed through the fell 12.

' t is obvious that b turning the sleeves [0 the wed es 8 will be rawn toward the rim 1 and Wil force and retain the edgesof the sheath 3;.between-the flangcsi! of the said rim 1. Also thesaid sleeves may be rotated in order to move the wedgcss away from the grimil fertile-purpose oi disconnecting the parts."

j The tube 6 1s circular in CIOSS-SBGIIOII and fits snugly within the sheath 3. It is also in contact with the outer facesof the wedges. so that it will be securely held in place withm the sheath. The outer faces of the wedges are concave transversely to conform to the circular cross section of-thc inner tube, and they are also curved lengthwise to conform to the contour of said tube, by reason of which a smooth surface is presented to the tube, and it is not bulged inwardly, whereby the entire resiliency of the tire is retained, and Wear is effectually prevented.

Having described our invention What We claim as new and desire to secure by Letters Patent is In a device of the class described, a telly and a rim mounted thereon, the telly having a radial opening reduced atits upper terminal to form an annular shoulder Within the open ing, and the rim having an opening alined with the reduced" portion of the opening in the telly, the edges of the rim being inbent to form flanges; a sheath having a cylindrical bore and being anteriorly broadened to engage the flanges and being provided upon its exterior with annular ribs to overlie the flanges, the said sheath being longitudinally slitted upon its inner face; a cylindrical tube niounted in the bore of the sheath; a headed tubular sleeve internally threaded and being journaled for rotation in the'oo'ening in the te y. the head of the sleeve eing arranged to engage the surface of the telly and the upper tenunal of the sleeve being arranged to eiy age the shoulder in the fclly simultaneously; a wedge disposed in the slit of the sheath. and having a curved upper face to engagethe tube, the said wedge having a.

threaded shank arranged to register in the opening in the rim and in the reduced portion of the opening in the telly and to en a 'e the sleeve; and a flexible lining disposed b e tween the sheath and the tube and between the wedge and the tube, the edges of the lining being prolonged to extend between the sheath and the rim and to inclose the bro ened portion of the sheath.

In testimony that We claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
